Benefits of technology

[0009] It is, therefore, the purpose of the invention to provide an insole for support of painful foot areas that is easy and fast to adjust in accordance with the needs of the patient and which can be provided at low cost. This purpose is achieved by an insole adjustment kit comprising an upper, elastic, cushioning insole layer and a lower, liquid filled insole layer under the upper layer and at least one pocket between the upper layer and the lower layer. The kit further comprising a number of inserts which are dimensioned for insertion into the pocket. The inserts have mutually different degrees of hardness.

Problems solved by technology

In addition, the liquid filled insole under the foot of the patient causes relatively large movements of the foot, even during very small changes of the point of gravity of the diabetic patient.

Embodiment Construction

[0036]FIG. 1a is a cross sectional view of an insole from a kit according to the invention. The upper layer 101, for example suitably made of polymer foam, has a first pocket 102 and a second pocket 103 between the upper layer 101 and a lower, liquid filled layer 107. The liquid filled layer may be made of two plastic sheets welded at the borders to provide a closed cavity filled with liquid, typically water.

[0037] The pockets 102 and 103 are provided as recesses in the upper layer 101. Inside the pocket 102 under the heel area, an insert 104 has been provided. In the pocket 103 under the forefoot, an insert 105 has been provided which has a perforation 106 in order to provide less pressure against the foot sole than the area surrounding the perforation 106.

[0038] As it appears in greater detail in FIG. 1b, the lower, liquid filled layer 107 is situated between fixation elements 108 and 109 in order to prevent that the lower layer 107 slides relatively to the upper layer 101. Afte...

Description

FIELD OF THE INVENTION [0001] The present invention relates to insoles with wound healing zones, predominantly for diabetes patients. BACKGROUND OF THE INVENTION [0002] Diabetes patients face a large risk to develop foot ulcers (decubitus) due to reduced blood circulation in the legs and the foot. Such wounds often lead to loss of job and social contact, and for the society it implies large costs. Investigations have shown that foot ulcers in the case of diabetics take on average 60 days to heal and with correspondingly large costs for wound healing medication and personnel during the healing period. Some wounds are not able to heal and develop in such a way that amputation of the foot or part of it is necessary. In Denmark, there are registered in the order of 10,000 open wounds among diabetics every year, and about 400 amputations are performed due to this cause. [0003] U.S. Pat. No. 5,329,705 discloses a footgear with an inner sole having a grid of removable, resilient elements t...
